GeneCardsP62
Human Protein AtlasP62
PB1 Domain (N-terminal, 1-122)Mediates self-oligomerization through front-to-back interactions. Enables p62 to form helical filaments and phase-separated condensates that concentrate cargo for autophagy.
ZZ Zinc Finger Domain (122-195)Binds to NEMO and RIPK1, linking p62 to NF-κB signaling.
TB Domain (195-255)Involved in TRAF6 binding and NF-κB activation.
KEAP1-Interacting Region (KIR, 347-356)Binds to KEAP1, competing with NRF2 and activating antioxidant responses.
UBA Domain (C-terminal, 386-440)Ubiquitin-associated domain that binds polyubiquitin chains (preferentially K63-linked and K48-linked) on cargo proteins.[@lamark2013]
Associated DiseasesAging, Als, Alzheimer, Amyotrophic Lateral Sclerosis, Ataxia
